The History of Freshman T.V. Shows.

Writer Oscar Hijuelos. His new novel, The Mambo Kings Play Songs of Love, is the story of Cuban immigrant brothers who work by day at grimy, exhausting jobs in a meat-packing house, but by night, in silk suits and lace ties, play the mambo, the vibrant, footloose music of Cuba. Surrounded by musicians wearing vests decorated with sequined palm trees, the Castillo brothers try to secure their own version of the American Dream. Their lives climax when they appear on the "I Love Lucy Show,".
